iOzzy, okay so the corrosion was around the touchscreen IC, should not interfere with your baseband. The missing part is reference designator C357 which is a 10UF 6.3V 20% capacitor in a 0402 package. It is part of the power management circuitry and should be replaced. check on U601_RF and may be a reflow would work.

Video before is for an ID lock, then You would have to replace all 3 of these chips.

In case You would want to replace only U601_RF -- you would have to replace rest of 2 chips. (BB and NAND)

U601_RF is a memory chip. It can be reflown. When U601_RF is removed - it will leave like a small platform under it. - glue residue. Do not take this off. You will rip the pads off. just flux, drag over the contacts with fresh solder, and put IC back.
